Module 7 Vocabulary

Across

3. triangular deposit, usually made up of silt and clay particles, that forms where a stream enters a large body of water
6. broad, flat, fertile area extending out from a stream's bank that is covered with water during floods
10. process by which precipitation that has fallen on land surfaces enters the ground and becomes groundwater
14. layer of impermeable material, such as silt, clay, or shale, that is a barrier to groundwater
15. the method of transport for all particles small enough to be held up by the turbulence of a stream's moving water
16. topography irregular topography with sinkholes, sinks, and sinking streams caused by groundwater dissolution of limestone.
17. curve or bend in a stream formed when a stream's slope decreases, water builds up in the stream channel, and moving water erodes away the sides of a streambed.
19. elevated land that divides one watershed from another
20. cone-shaped or cylindrical dripstone deposit of calcium carbonate that hangs like an icicle from a cave's ceiling
21. a natural underground opening connected to Earth's surface, usually formed when groundwater dissolves limestone.
22. measure of a volume of stream water that flows over a specific location in a particular amount of time
23. load describes sediments that are too heavy or large to be kept in suspension or solution and are pushed or rolled along the bottom of a strembed
25. of saturation region below Earth's surface where all the pores of a material are completely filled with goundwater
26. of aeration region above the water table where materials are moist, but pores contain mostly air
27. natural or human-made body of water that can form when a depression on land fills with water
29. table upper boundary of the zone of saturation that rises during wet seasons and drop during day periods
31. process by which a stream resumes downcutting toward its base level, increasing its rate of flow.
33. potentially devastating natural occurrence in which water spills over the sides of stream's banks onto adjacent land areas
34. permeable underground layer through which groundwater flows relatively easily

Down

1. level the elevation at which a stream enters another stream or body of water
2. mound-shaped dripstone deposit of calcium carbonate that forms on a cave's floor beneath a stalactite
4. explosive hot spring that erups regularly
5. process by which lakes become rich in nutrients from the surrounding watershed, resulting in a charge in the kinds of organisms in the lake.
7. difference between the water level in a pumped well and the original water-table level.
8. deep hole drilled or dug into the ground to reach a reservoir of groundwater
9. well fountain of water that spurts above the land surface when a well taps a confined aquifer containing water under pressure
11. channel narrow pathway carved into sediment or rock by the movement of surface water
12. ability of a material to let water pass through; is a high material with large, well-connected pores and low in material with few pores or small pores
13. bank ground bordering each side of a stream that keeps the moving water confined
15. natural discharge of groundwater at Earth's surface where an aquifer and an aquiclude come in contact
18. process by which water from precipitation and runoff is added to the zone of saturation
24. any land area, such as a bog or marsh, that is covered in water a large part of the year and supports specific plant species
28. depression in Earth's surface formed when a cave collapses or bedrock is dissolved by acidic rain or moist soil
29. land area drained by a stream system
30. water that flows downslope on Earth's surface and may enter a stream, or lake; its rate is influenced by the angle of slope, vegetation, rate of precipitation, and soil composition
32. spring thermal spring with temperatures higher than that of the human body
